Baseline Left Ventricular d <i>P</i> /d <i>t</i> max Rather than the Acute Improvement in d <i>P</i> /d <i>t</i> max Predicts Clinical Outcome in Patients with Cardiac Resynchronization Therapy

Abstract

Left ventricular dP/dt(max) measured at baseline and during CRT are predictors of 1-year survival free from all-cause mortality, HTX, or LVAD implantation, but the acute improvement in dP/dt(max) is not correlated to clinical outcome.
